摘要:
A door hinge device includes a hinge shaft fixed to a body of an appliance and having a damping protrusion on one side of an outer surface, and a coupling member having a shaft engaging hole coupled to an outer surface of the hinge shaft. The shaft engaging hole includes a holding portion having an inner diameter corresponding to an outer diameter of the hinge shaft and a damping portion having a larger inner diameter than the outer diameter of the hinge shaft and surrounding the damping protrusion. The damping portion includes a separation section separated from the damping protrusion when the door is closed, and a contact section contacting the damping protrusion when the door is opened. The door hinge device can prevent slamming or trembling when the door is opened or closed, and has a simple configuration.

A blind modulation classification apparatus in a satellite communication system improves performance in non-ideal communication environment having frequency error and phase error, by reducing computational burden of test statistic and possibility of numerical error of hardware, with computation of likelihood for each stage independently. The blind modulation classification apparatus includes a plurality of likelihood computing units, each for computing a likelihood value of a received baseband signal for corresponding one of a plurality of modulation schemes; a maximum selecting and setting units for selecting the maximum among the calculated likelihood values and setting a flag corresponding to the maximum to ‘1’ and the other flags to ‘0’; a plurality of flag summing-up units for summing up the flags of the plurality of the modulation schemes; and a modulation scheme selecting unit for selecting the maximum among the summed-up values and selecting the modulation scheme corresponding to the selected value.

A sweatband used for headwear that is woven of 100% combustible synthetic yarn without any polyurethane. The sweatband provides excellent sweat absorbing capability and exhibits good elasticity through the structure of the textile without imposing undue pressure on the wearer so that the sweatband may be worn comfortably for a long period of time. The yarn used to produce the sweatband is passed through a bulky process, being shrunk through a low temperature short-term combustion method and dry heat treatment process after weaving. The sweatband preferably has a unitary, single ply construction that is planar and does not twist in the absence of elongating force.

Disclosed is a micro actuator and an ink jet printer head manufactured using the same. The micro actuator comprises a substrate having a space part which is integrally defined in the substrate and is opened only at a lower end thereof; a first piezoelectric element formed on the substrate in a first area which is arranged above the space part and actuated when voltage is applied thereto; a second piezoelectric element formed on the substrate in a second area which is not arranged above the space part and not actuated even when voltage is applied thereto; and an upper electrode formed on the first piezoelectric element; whereby rigidity of an entire structure is elevated and panel vibration is reduced, by the second piezoelectric element.

Disclosed is an ink jet printer head actuator and a manufacturing method thereof. The ink jet printer head actuator comprises a vibrating plate, a portion of a plate surface of the vibrating plate being mechanically deformed by an external force; a chamber plate formed with a plurality of chambers, the chamber plate sucking and discharging ink into and out of the plurality of chambers by vibration of the vibrating plate; a protective thin film intervened between the vibrating plate and the chamber plate for preventing the vibrating plate from being etched when the plurality of chambers are formed in the chamber plate and for preventing the vibrating plate from being corroded by keeping ink in the plurality of chambers from being brought into contact with the vibrating plate; a plurality of piezoelectric elements attached to a surface of the vibrating plate for vibrating portions of the vibrating plate which correspond to the plurality of chambers, respectively, while being deformed in a lengthwise direction depending upon electric power supply; and a plurality of electrodes at least laminated on the plurality of piezoelectric elements for supplying electric power thereto, respectively. In the manufacturing method, a protective thin film of gold acts as an etch stop layer while etching the chamber plate of nickel relative to the vibrating plate of nickel.

An emergency sign with orientable light assemblies is an apparatus that displays a message or instructions and alerts nearby individuals of an emergency or event. The apparatus includes a sign, a first orientable light assembly, and a second orientable light assembly. The first orientable light assembly and the second orientable light assembly each include a brace, a post, a sleeve, a carriage, a track, and a light fixture. The first orientable light assembly and the second orientable light are mounted onto the sign and are opposite each other about the sign. The brace positions the light fixture about the sign. The sleeve integrated into the brace and the post is rotatably connected within the sleeve so that the light fixture may spin. The carriage is terminally mounted to the post and the track is integrated into the light fixture so that the light fixture may laterally slide.

A method of manufacturing an ink-jet printhead, including forming an insulation film on a substrate, depositing a metal layer onto said insulation film and patterning said metal layer to form a heater, forming an electrical wire on said substrate, etching said substrate at a predetermined depth from a top surface of said substrate in a direction perpendicular to a major surface of said heater to form a narrow passage, depositing an ink chamber barrier layer on said top surface of said substrate and patterning said ink chamber barrier layer to form an ink chamber, stacking a nozzle plate having a nozzle on said ink chamber barrier layer and disposed on an upper portion of said ink chamber barrier layer, and applying predetermined pressure and temperature onto said nozzle plate to bond said nozzle plate and said substrate, and etching said substrate from a bottom surface thereof to form a wide passage communicating with said narrow passage.
摘要:
The present invention provides peptide complexes comprising phospholipase D and one or morephospholipase D-interacting peptides. The peptide complexes are useful in screening assays foridentifying compounds effective in modulating the peptide complexes and in treating and/or preventing diseases associated with phospholipase D and it's interacting partners. In addition, methods for screening modulators of the peptide complexes or interacting members thereof are provided.
